ABSTRACT:
An electric slider comprises a plurality of independently springing, aligned, uniformly spaced contact elements mechanically and electrically connected to one another. Each contact element is of elongated C shape having a discontinuity at one of its short sides. Each contact element comprises a base portion at which the contact element is connected to an adjoining contact element, a contact portion and a springing portion connecting the contact portion with the base portion. The contact portion is of circular cross section and at least part of the springing portion along a long side of the contact element is of flattened cross section. The plane of the flattened cross section is so oriented that the springing portion has, in the direction perpendicular to the slider motion, a moment of inertia that is larger than that of a circular cross section and, in the direction determining the resilient pressure, has a moment of inertia that is smaller than that of a circular cross section.
